Over the past 7 years, I've tried every time management/billing app out there for freelancers. They all had some good features and some drawbacks. Studiometry is all good, and as close to "perfect" as you can get for under $50. Everything else is in the trash, this is the app I'm using for now on. Congratulations, Tom. I started using this with the first beta and you were so incredibly responsive to everyone's suggestions and kept making the application better and better. Thanks!
